While making his grand tour of European archives to research the Brunswick family history that he never completed, Leibniz stopped in [[Vienna]] between May 1688 and February 1689, where he did much legal and diplomatic work for the Brunswicks. He visited mines, talked with mine engineers, and tried to negotiate export contracts for lead from the ducal mines in the [[Harz mountains]]. His proposal that the streets of Vienna be lit with lamps burning [[rapeseed oil]] was implemented. During a formal audience with the [[Holy Roman Emperor|Austrian Emperor]] and in subsequent memoranda, he advocated reorganizing the Austrian economy, reforming the coinage of much of central Europe, negotiating a [[Concordat]] between the [[Habsburg]]s and the [[Holy See|Vatican]], and creating an imperial research library, official archive, and public insurance fund. He wrote and published an important paper on [[mechanics]].
